What should i expect to pay to have my tie rods and idler arms replaced (whats the normal price range to have those installed) ?

 

With labor and parts, expect to pay in the $500 range. If you buy the parts seperately and take them somewhere yo be put in, you can save from $50 to $75 off of that just by avoiding their parts markup. If you do it yourself, you'd save probably $250 and only be out some of the special tools you'll need to do it.
